Subject: [PATCH 4.1 27/78] ARM: imx6: correct i.MX6 PCIe interrupt routing

4.1-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Lucas Stach <l.stach@...gutronix.de>

commit 1a9fa190956f45c1e58c4d8bfa5ac051691ea590 upstream.

The PCIe interrupts are also routed through the GPC. This has been
missed from the conversion to stacked IRQ domains as the PCIe
controller uses an explicit interrupt map and thus doesn't inherit
the SoC global interrupt parent.
